DNA recovery from latent fingermarks treated with an infrared fluorescent fingerprint powder

Fingermarks have been used for over 100 years as a means of identifying individuals involved in crime, by virtue of the patterns deposited at crime scenes or on items of evidential value [1]. In 1997, van Oorschot et al. [2] demonstrated that fingermark residues also provide enough DNA for the generation of DNA profiles. Technological and scientific advances have improved the ability to obtain at least partial DNA profiles from evidence handled by an individual, primarily through the increased sensitivity in DNA typing procedures.
